For video editing, the software must support gpu accelerated enc/decoding, else you prolly need threadripper but also slower than gpu acceleration
Check the ram usage, most likely the cpu doing all the works which cause the slow down, ram usage overload mostly will cause the app to crash only.
Video editing rarely use a lot of ram especially 1080p only.

Gpu acceleration is the way to go, nowadays not only video playback are gpu accelerated, web layout, font rendering, compositing, css animation and so on on your web browser, are already accelerated by GPU.

If you don't overclocking stock cooler is fine, amd cpu is slightly warmer as indicated on some review site.
And if you game on 1080p and above, the fps difference become minimal on both cpu, of course intel ipc still the king,

i dont know both cpu either, just watched some video lol https://www.google.com/search?q=intel%20870...vs%20r7%202700x

One single fan can hardly improve.
, you need at least 6 fans to improve ventilation.
The case i bought always has side panel fans, and top panel fans, 3 front intake is a must.
Even with stock cooler my 65w Ryzen only idle at ~37c, 40 to 50 on load.

With my Fractal design R6, my cpu idle at 32c (360 aio), Vega 64 idle at 36c only.

Also make sure the CPU Vcore is not set too auto, some board will increase vcore without good reason, like my B350 Mortar arctic,
The increased vcore will increase heat output as well.

What is your case?
because intake usually is filtered, meaning weaker air flow, that is why intake need at least 3.
one single fan can improve only if it's high airflow fan, Aka the infamous Delta, usually known with at least 260 cfm lol

or just upgrade your casing

3 months later back with square one, because heatsink is full of dust lol

Delta fans with PWM can be tamed with pwm + 45 watt fan controller, but if your delta is 3 pins type, can only be used as emergency cooling lol (activate when temp reach critical.)

you can add 2 140mm fans but with at least 2000 rpm, larger fan has lower pitch noise than 120/92mm counterpart, but with lower static pressure.
top fan can be switch to intake, at least the cpu has fresh air. and rear exhaust remain same, but remember, hot air rise.

https://www.silverstonetek.com/product.php?pid=366&area=en this one is 38mm thick, so check clearance first.

Most people be like, i got R6 2600 and some thousand dollar GPU but using cheap casing, later will complaint pc running too hot.
Case cooling performance are most often ignored when people buying new casing.

Open air casing depends on environment, my area definitely cannot due to sticky yellow dust, it does not work with everyone.

Also buying the Noctua definitely is an investment, the fans has 6 years warranty and very long life, Thought Im only like noctua lol,
also i'm not aware of any other brands that make 140mm fan with 2000 RPM.

This sounds a bit unrealistic, what about GPU?
Most gpu dumps heats back into casing, even blower type gpu still radiate heat.

I'm favor for silence cooling hence the multiple fans.

Suggesting 2x120mm fan is enough without any recommendation isn't very convincing .

I own a lot of fans, seriously, i can build a casing with just fans, lol

For silent fan spins at 5V,
1. Gelid series
2. Xigmatek
3. Fractal Design 12/14cm
4. Silverstone 141AP, but noisy at full speed, Noctua P14 also fall into this category, high start up voltage.

Exotic fan / Rare
Noiseblocker, the cheaper series perform quite well, also owned the multiframe S series, good shit
Prolimatech USV14,
Sony SFF21C/ Scythe S-FLEX, still have few of them,
NMB Matsushita (Panasonic), the 12v fans also good, plenty of airflow even at 5v.
San Ace also good, used a while and sold them off, also goodding lol.
Nidec Servo Gentle Typhoon

Those rare 12cm fans i owned perform really well, better than those branded fans. although some of them are industrial/OEM fan.
14cm fans i have no recommendation, need to try out more 14cm fans.

Generally, low powered fan will works even at 5V, those below 1A will always work and can be powered up with just USB cable.

the stock cooler is just a chunk of aluminum block with 2k rpm silent fan
while beneath it is a 6 cores 95w cpu, it will do fine if you put it into a fridge

Which compiler generate segfault and what version,
pretty sure they patched it fast as GCC 9.1 just released.

For me i would just try different build rather than waiting for patches.

Most games are still runs better on Nvidia GPU due to more raw power, thats a hard-to-swallow pill.
unless your games use Vulkan, AMD GPU runs much faster with Vulkan Renderer.

Another positive points for AMD GPU is Radeon Chill, built in overclocking and tweakin, FreeSync2.

RTX may be cool but iirc it still cant run most game smoothly with highest RT quality.

That's a lot for AMD processor already, also quite impressive consider only one generation gap.

Damn, I got this board like almost 2 years and ryzen 3000 I supported, daaaammmnnn

if this is about flashing bios with zen 2 cpu support, raid doesn't work yet.
at least on my b350 mortar artic

Depends on the production date?
if your mobo does not support BIOS flashback, you need a cpu to update BIOS, https://www.msi.com/blog/the-latest-bios-fo...ies-motherboard

If you have low speed fan, it wont be audible,
I have one server fan, it will ramp up the speed to 100% for less than a second before going down, no matter what mobo i use.
